Title: Digital broadcasting system and data processing method
Inventor: LEE HYOUNG GON
IPC: H04N19/89
Filed: 2006-12-20
Abstract: A digital broadcasting system and a data processing method are provided to improve receiving performance by performing the additional encoding of mobile service data and transmitting the encoded data. An M-VSB(Vestigial Side Band) pre-processor(202) performs the first coding of mobile service data, and forms a data group including a plurality of the encoded mobile service data packets. A multiplexer(203) multiplexes the mobile service data packets of the data group outputted from the M-VSB pre-processor and a main service data packet as a burst structure. An information former(204) inserts information for initializing a trellis encoder and time and frequency information for an SFN(Single Frequency Network) into a predetermined data packet among the multiplexed data packets. An RS(Reed Solomon) encoder(206) performs the second coding and the trellis coding of the output data packets of the multiplexer and the information former, generates data for initializing a memory of a trellis encoding unit in a start time of a known data string, and changes input data of the trellis encoding unit. A modifier and sync inserter(214) transmits the change data, changes information for the initialization as state information of the trellis encoding unit, generates identification information indicating a field synchronous insertion time, and transmits the generated identification signal to each transmitter.

Title: Radio transmission control method, radio receiver apparatus, and radio transmitter apparatus
Inventor: HARA YOSHITAKA
IPC: H04B7/26
Filed: 2004-07-29
Abstract: Conventionally, if the number of transmission antennas is greater than that of reception antennas, different signals simultaneously transmitted from the transmission antennas cannot be separated from one another at the receiving end, resulting in a significant degradation of received-signal quality. A transmitter and a receiver each have a plurality of antennas. The transmitter transmits a pilot signal. The receiver receives the pilot signal to calculate transmission-related information corresponding to the pilot signal, and then selects, based on this calculated information, a signal to be sent to and utilized by the transmitter. The receiver then informs the selected signal to the transmitter. The transmitter selects, from the informed signal, transmission antennas and uses them to transmit information signals, so that a signal separation can be easily performed at the receiving end.

Title: Method and apparatus for smoothing overall quality of video transported over a wireless medium
Inventor: VAN DER STOK PETRUS DESIDERIUS
IPC: H04N7/24
Filed: 2004-11-11
Abstract: A system and method for controlling a scalable video application by modeling it as a Markov decision process. The model is based on measuring the relative progress of the application, where relative progress is the difference between the allocated CPU budget for processing a frame and the actual CPU cycles used in processing a frame. The control strategy is based on the number of levels most recently decoded and the maximum levels that can be decoded for the next frame based on the number of received layers (the maximum quality level) and the budgeted CPU time. The object is to smooth quality transitions between frames by developing a quality level control strategy that minimizes both the number of deadline misses (frame not fully decoded) and the number of quality level changes, while maximizing the quality level. The fewer the number of quality level changes, the smoother the image viewed.
